- Notes
- Studebaker-Packard Service Bulletin No. 319 identifies a 1957 Twin-Traction passenger car by a red sticker on the rear face of the front door above the lock and a small differential-housing-cover tag stamped T. The T tag is separate from the regular rear-axle ratio tag, and the bulletin directs technicians to replace both tags after service. Missing tags do not by themselves prove the axle was never Twin-Traction; reconcile them with the production order and installed hardware.
